“I have received this great fiery Spirit: receive him now yourselves. If you wish to receive him that he may dwell in you, first offer hard labours of the flesh and humility of the heart. Raise your thoughts up to heaven night and day. Ask in uprightness of heart for this fiery Spirit and he will be given you….Persist in prayer diligently, with all your heart, and he will be given you, for this Spirit dwells in upright hearts. He will reveal to you higher mysteries and other things which I cannot express in ink and paper…Celestial joy will then be your portion day and night.
-St. Antony the Great
